-that is reversed in chickens (versus human genetics). In chickens the Male has two copies of the sex-chromosome. In humans the Female has two copies of the Sex-chromosome.

 

Therefore if the Dom was the MOTHER, you CAN ONLY have a heterozygous male.
If the Dom is the FATHER, females will have one copy of the Sex-linked gene/chromosome/allele, for sure.


If the Dominique (the barred bird) was the mother, and the EE (non-barred bird) was the father, the chick in question would be male. That's the entire basis of the black sex link industry. A female chick from that pairing would not be barred. It would have  a solid dark head at hatch. A non-barred male over a barred female is the classic, genetically proven black sex link. That's why I asked which parent was which in the first place. If you're disputing how black sex linkage works, you need to study the link junebuggena gave you.

 

I stand by my statement. "Everyone" agreed with me cause I'm right :D
